Question
A factory requires 42 machines to produce a given number of articles in 63 days.
The number of machines required to produce the same number of articles in 54 days is 48.
The number of machines required to produce the same number of articles in 54 days is 48.
Answer: Option B
:
B
Let the required number of machines be denoted by 'n' and number of days taken be 'd'.
As number of machines increases, the number of days required to make articles decreases, hence they are inversely proportional.
n×d = constant
n1×d1=n2×d2
Using inverse proportion condition,
42n = 5463
n=42×6354
n = 49
So, 49 machines are required.
Hence, the statement is false.
